These two equations concern a lab on the measurement of E/M by the Brainbridge Method.

I need to derive the absolute error for two different equations,

the first one is: e/m = 2V/B2R2

treat (e/m) as a SINGLE VARIABLE when doing the derivation.

The second is B=8μ0N(I-Io) / √125a

whre μo=4π*10-7 T*m/A

Io=zero referenc current

You may want to EXPLICITLY substitute in a new variable, (Inet), in place of (I – Io) [ie, let Inet = I – Io]

- Physics. Error equations. Please help! -
